are not half as long as the fore wings, which are rather broad 

 while the hind pair are lanceolate. 



"■Tiie larv{\3 mine very narrow serpentine paths in the inte- 

 rior of leaves, the mine being always on the npper surface. 

 They vary much in form, l)eing sometimes a slender galler^'^ or 

 line, either sim[)le, or enlarged towards the end into a blotch. 

 When the larva is full-fed it quits the mine, cutting for this 

 purpose the separated cuticle, in order to Aveave a minute co- 

 coon." (Clemens.) N, conjiifoliella Clemens mines the hazel. 

 N. ])kitanella Clemens mines the button-wood tree, or syca- 

 more, and N. amelanchierella Clemens mines the leaves of the 

 June berry in June and July. 



Pterophorid.e Latreille. The small group of PIvme-moths 

 may be at once known b}^ their fissured and plumed wings. 

 The body is long and slender, with long antennai and legs. 

 They are the lowest moths, the long slender abdomen and fis- 

 sured Aviugs being marks of degradation. The larvae have six- 

 teen legs and are rather hairy. They form no cocoon, but, 

 fastening themselves b}' the tail to a leaf or stem, shed their 

 larva-skins and appear in the pupa state. Some of the pupse 

 are nearly as hair}' as the larvae, others are quite naked. Most 

 of the larvie feed in the earl}' summer months, and the perfect 

 insects appear rather later, though some may be seen in spring. 

 (Stainton, Manual of British Butterflies and Moths.) 



In PterojyJiorus the hind margin of the fore wing is more or 

 less deeply cleft, while the hind wings are almost divided into 

 three separate slender lobes or plumes. The larvie live in the 

 flowers and stems as well as on the leaves of plants. P. peri- 

 scelidactylns Fitch (Plate 8, fig. 23 ; a, larva ; &, pupa, enlarged) 

 is tawny yellow, the fore wings having three large white spots 

 and two bands beyond ; the outer line is thread-like, the inner 

 line being much broader on the costal division of the wing, re- 

 appearing at the base of the split in the wing, and below 

 extending out to the lower half of the outer line. The hind 

 wings are darker brown than the rest of the moth, while the 

 third and shortest division of the wing is white, but brown at 

 the end, with the fringe on the outer fourth of the wing still 

 darker brown. The legs are white with tufts of brown scales
